Homology modulo 2,y so that it applies to unoriented simplicial complexes. Roughly speaking if an oriented simplex a and the same simplex with opposite orientation, -σ, are to be regarded as giving the same chain, then −1 = +1 and so the coefficients must be regarded as lying in the group (or field) ZZ. instead of inchuckle 发表于 2025-3-26 18:06:20
